Electric and Magnetic Field Measurement

Applications

The EFA-300 is an ideal field analyzer for measuring magnetic and electric fields in

the workplace and in public spaces. It is designed for professional users in the power

industry, at municipal utilities, by insurers, and for health and safety professionals in

industry. In the low frequency range, it handles virtually any required measurement,

simply and precisely. This instrument provides field analysis using an FFT computa-

tion in addition to measuring magnetic and electric fields. The innovative STD mode

opens up further application areas. With this new mode the measurement results for

magnetic and electric field strength are displayed as a Percent of Standard, regardless

of the signal shape. This mode enables fast and reliable measurement and evalua-

tion of the typical fields where complex, non-sinusoidal signals are common, e.g., in

industrial applications that use resistance welding. Resistance welding issues surface

in the traditional 50/60 Hz systems as well as in the newer medium-frequency switch-

ing units.

Basic Operation

The EFA-300 has a built-in, isotropic, magnetic field probe. Optional external probes

can be used to handle other applications. For example, an isotropic B-field probe with

high sensitivity and a large (100 cm

) cross-sectional area is available for the standard-

ized measurement of dissimilar magnetic fields.

For measurements in hard-to-reach places, a miniature 3 cm diameter B-field “sniffer”

probe is available.

The EFA-300 includes a cubic-shaped, isotropic, E-field module. This E-field module

contains both the sensor and circuitry that allows it to be operated independent of

the base unit. The base instrument, or a computer with the EFA-TS remote software,

can be used to read results in real-time and control the functions of the module. In the

data-logging mode, the E-field module can be operated independently. Stored data

can be read and analyzed at a later date using a computer and the EFA-TS software.

The major advantage of operating the E-field module remotely is that it greatly reduc-

es the influence of the human body on the electric field you are trying to measure.
